CORNER-STAYING MACHINE.

Specification of Letters Patent.

Patented Oct. 26, 1909.

Application filed April 22, 1904. Serial No. 204,422.

To all whom it may concern:

Be it known that I, VILLIAM F. MORSE, of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Corner-Staying Machine, of which the following is a specification.

This invention has for its object the production of a corner-staying machine, which is particularly simple in construction and efficient in operation; and to this end, it consists in the combinations, constructions and arrangements of the component parts of a corner-staying machine, as hereinafter fully set forth and pointed out in the claims.

In describing this invention, reference is had to the accompanying drawings, in which like characters designate corresponding parts in all the views.

Figures 1 and 2 are, respectively, front and slde elevations of a referable embod1- ment of this invention. Flg. 3 is an enlarged sectional View, partly broken away, taken on line AA, Fig. 1. Figs. 41 and '5 are, re-

spectively, front and side elevations, partly tions of one of the supports for the article to be stayed, the engaging part cooperating therewith, and contiguous portions of the machine. Fig. 8 is a face View of one of the cams i for controlling the feed of the strlps from which the stays are cut. Figs. 9 and 10 are face views of the cams for raising and lowering one of the engaging parts, and for moving the same laterally. Figs. 11 and 12 are, respectively, side and front elevations of a portion of a modified construction of this machine. Fig, 13 is a side elevation of the means shown in Figs. 11 and 12, the engaging part being illustrated as cooperating with the side of the support.

The preferable embodiment of this invention comprises a pair of supports 1 2 for opposite corners to be stayed, engaging parts 3 1, one for each support, means for supplying adhesive pieces or stays to the corners, and means for effecting the cooperation of said supports and engaging parts to afiix the stays. During the operation of the illustrated construction of the machine, the supports 1 2 are stationary, and each engaging part cooperates successivelywith a plurality of engaging faces of the corresponding support for attaching a stay. Although a pair of supports 1 2' are preferably used, it will be obvious to those skilled in the art that one of said supports and the corresponding engaging part may be dispensed with, if desired.

As shown in Figs. 1 and 2, the supports 1 2 project beyond the front faces of an upright 5 fixed to a suitable frame 6, and of a carriage 7 movable crosswise in the frame 6 toward and from the upright 5 by any de sirable means, as a feed-screw 8. Said supports are generally movable lengthwise, or

forwardly, by any suitable means, as gearwheels 9 indicated by dotted lines, Fig. 2, for varying'the amount of projection of the supports beyond the front faces of the upright 5 and the carriage 7 in conformity with the depth of the article, as a boX, to be provided with stays, it being understood that the contiguous edges of sides of the box ordinarily engage the front faces of said upright and carriage. These supports 1 2 are usually of rectangular cross-section and are provided with engaging faces 10' at their tops arranged in substantially the same horizontal plane, and with additional engaging faces 11 attheir outer sides disposed in substantially vertical planes. In order to facilitate the arrangement upon the supports 1 2 of the article to .be stayed, the front faces of .the upright 5 and the carriage 7 are provided with forwardly-projecting arms 12 having their lower faces inclined downwardly from their free ends toward a horizontal plane coincident with the faces 10 of said supports.

As best seen in Fig. 1, the engaging parts 3 4 are normally arranged with their lower faces in substantially horizontal planes opposed to the faces 10 of the supports 1 2 and ntending beyond the inner and outer sides of vertical planes forming continuations of the faces 11 of said supports, and are preferably supported by the lower ends of plungers comprising main bodies 13 14, Figs. 6 and 7, pivoted at their upper ends at 15 to vertically reciprocating heads 16 17, and members 18 19 reciprocally-movable relatively to the main bodies 13 14 and pivoted at their lower ends at 20 21 to said engaging parts, the pivots 2O 21 being above and opposed to the faces 10 of the supports 1 2, and at the inner sides of vertical planes forming continuations of the faces 11, both when the engaging parts are in their normal position, as illustrated in Fig. 1, and when said parts are cooperating with the faces 10. Said engaging parts 3 4 are held in their normal position relatively to their supporting plungers by springs 22 having opposite ends con-.

nected, respectively, to the engaging parts 3 4 and the main bodies 13 14. The outer sides of the engaging parts 3 4 projecting laterally beyond vertical planes forming continuations of the faces 11, are provided with cutouts 23 in their lower or working faces and with stay-supports 24 which usually consist of fiat strips movable into and out of the cutouts 23 and carried by arms 25 that are reciprocally-movable in bearings 26 provided on the engaging parts 3 4, and are formed with enlarged upper ends for engaging the top faces of the bearings 26 and limiting the downward movement of the staysupports relatively to the engaging parts. Suitable springs 27 engaged with the enlarged ends of the arms 25 hold the staysupports in their normal position with their upper faces beneath the working faces of the engaging parts 3 4, and yield freely to permit the stay-supports to enter the cutouts 23. In operation the lower or working face of each engaging part cooperates throughout its entire extent successively with the engaging faces of the support.

The main bodies 13 14 of the plungers supporting the engaging parts 3 4 are formed with upright openings 28, Fig. 4, and with laterally-extending branches 29, Fig. 5, at their upper ends'forming supports for the pivots 15; and the'members 18 19 extend lengthwise of the o enings 28 and above and below the same, t ieir upper ends being provided with adjustable shoulders 30 movable into and out of engagement with upper faces of the main bodies 13 14, and their lower ends being provided with the pivots 20 21 and with shoulders 31 movable into and out of engagement with lower faces of said main bodies. Springs 32 are arranged within the openings 28 around the members 18 19 between shoulders, provided, respectively, on the lower ends of said members 18 19 and within the upper ends of the openings 28, and operate to hold the members 18 19 in their normal position with their shoulders 30 engaged with upper faces of the main bodies 13 14 and their shoulders 31 separated from lower faces of said main bodies. The amount of separation of the shoulders 31 from the opposing lower faces of the main bodies 13 14 may be regulated by adjusting shoulders 30.

The means for supplying adhesive pieces or stays to the corners onthe supports 1 2 consists of reels 33, moistening devices, feeding devices, and cutting means. Said reels 33 are of any desirable form, sizeand construction for receiving and supporting the adhesive strips. As illustrated, the moistening devices each consist of a fluid-containing reservoir 34 adjustable relatively to the frame 6 and suitably secured in position, a roller 35 movable in the reservoir 34 and engaging the lower face of the corresponding adhesive strip for applying a moistening fluid thereto, a guide-roller 36, a pressureroller 37 engaging the'upper face of the strip above the roller 35, and a spring arm 38 for forcing the roller 37 toward the roller 35. Each roller 35 is formed with a groove, not illustrated, in its periphery in order that the portion of the adhesive strip movable in. alinement with this groove may be unprovided with the moistening fluid. Said rollers 35 thus moisten separated portions of the adhesive strips. 7

The feeding devices are of any desirable form, size and construction, are supported respectively'by the upright 5 and the carriage 7, and are each here shown as comprising opposing rollers 39 40, the rollers 39 being adjustable toward and from the rollers 40 in any desirable manner, unnecessary to herein set forth, for varying the frictional force with which said rollers engage the adhesive strips, and the rollers 40 being fixed to corresponding ends of shafts 41 which are journaled respectively in the upright 5 and the carriage 7, and are each provided with a loose gear-wheel 42 connected thereto by any suitable ratchet-wheel mechanism, unnecessary to herein illustrate and describe, for intermittently advancing said shafts 41. Each of the gear-wheels 42 is actuated by a rocking part, as a toothed segment 43, connected to one end of a link 44, the other end of which is adjustable lengthwise of one end of a rocking lever 45 having its other end engaged by a cam 46 on the shaft 47. The cam 46 for actuating the feeding device sup; ported by the carriage 7 is engaged by an arm 48 provided on said carriage, for mov ing this cam lengthwise of the shaft 47 with the carriage 7. It will be apparent, however, to those skilled in the art, that the means for actuating one of the gear-wheels 42 may be omitted and both gear-wheels 42 mounted on the same shaft 41, in which event this shaft will be elongated and the gear-wheel 42 supported by the carriage 7 will slide lengthwise of said shaft. The adhesive strips when fed beyond the rollers 39 40, are usually guided by lower and upper separated bars 49 50 which extend lengthwise of the path of movement of said ing on the horizontal face of the support,

strips, register with annular grooves in the rollers 39, 40, and terminate in close proximity to the stay-supports 24, the ends of the bars 49 adjacent the stay-supports 24 being unsupported and composed of spring material.

The cutting means for severing the adhesive strips into pieces or stays is here illustrated as knives 51 52, fixed, respectively, to the supports 1 2, and to the plungers supporting the engaging parts 3 4, and having their cutting edges arranged substantially parallel with the faces 10 of the supports 1 2. Said knives 52 are guided in their movement by arms 53 projecting above the faces 10 and extending rearwardly toward their upper edges. The cutting edges of the knives 51 are preferably arranged below the adjacent unsupported ends of the bars 49, and, consequently, the downward movement of the knives 52 slightly depresses said ends of the bars 49, which immediately spring upwardly after the operation of the knives 51 52, and thus elevate above the knives 51 the advance ends of the strips from which the stays are to be cut and prevent adhesion of said advance ends to the knives 51.

In the preferable construction of this invention, the means for effecting the coijperation of the supports 1 2 and the engaging parts 3 4 to afiix the stays, consists of the plungers and heads previously described for supporting and reciprocating the engaging parts 3 4, means for actuating the heads, and means for moving laterally the free or lower ends of the plungers. Said means for actuating the heads 16 17 consists of cams 55 revoluble with the shaft 47 and engaging rollers 54 provided on detachable extensions of said heads formed with lengthwise slots 56 for receiving the shaft 47. During a complete revolution of the shaft 47 the cams 55 move th heads 16 17 downwardly to a plane intermediate of their upper and lower positions to non-slidably engage and compress the stay upon the side of the box restthen slightly raise the heads, and finally depress said heads to the limit of their movement to cause the engaging part to slidably engage the stay upon the side of the face supported on the vertical face of the sup-- port and return the heads to their normal elevated position. The shaft 47 is normally stationary and is actuated to make intermittent revolutions by a constantly revolving pulley 57, Fig. 1, and any desirable clutch, not illustrated, interposed between said shaft and pulley and controlled by a treadle 58. Upon the completion of each revolution of the shaft 47 retrograde movement thereof is prevented by a pawl 59 pivoted to a suitable support between its ends and having one extremity connected to a spring 60, and its other extremity normally in contact with the periphery of a disk 61 and movable toward the axis of the disk into engagement with a shoulder 62 thereof extending inwardly from said periphery. Two of the disks 61 are fixed to the shaft 47, each being provided on one face with one of the cams 55, and on its other face with an additional cam 63, and the disk 61 cotiperating with the pawl 59 is formed with an inclined surface 64 which extends outwardly from the inner end of the shoulder 62 to the periphery of said disk.

As best seen in Figs. 4, 5, 6 and 7, the means for moving laterally the free or lower ends of the plungers supporting the engaging parts 3 4 consists of plungers 65 for moving these ends of the plungers in one direction, and springs 66 and cams 67 for moving said ends in the reverse direction. The plungers 65 are supported by the upright 5 and the carriage 7, are reciprocally movable into and out of engagement with rollers 68 on the main bodies 13 14 in planes disposed at substantially right-angles with the downward path of movement of said main bodies, and are actuated by the cams 63 and levers 69 pivoted intermediate of their ends'to suitable supports, and having their upper ends engaged with the cams 63, and their lower ends pivoted to the plungers 65. Said cams 63 are so constructed that just before the cams 67 operate to move the engaging parts 3 4 laterally, the plungers 65 are caused to commence their return movement from the rollers 68. The springs 66 are mounted on rods 7 0 extending through the main bodies 13 14 and having corresponding ends fixed to the heads 16 17, and are interposed between shoulders 71 on the free ends of said rods and opposing surfaces of the main bodies 13 14. The cams 67 are fixed to the main bodies 13 14, are preferably provided on the lower ends of parts 72 adjustable lengthwise of said main bodies and cotiperate with rollers 73 fixed to the upright 5 and the carriage 7.

In Figs. 11, 12 and 13 is illustrated a modified construction of a plunger 74 for the engaging part 75. The plunger 74 is pivoted at its upper end to the head 76 and is secured at its lower end to the engaging part 75 by a pivot 77 normally arranged at the outer side of a vertical plane forming a continuation of the outer face 78 of the support 79. Springs 80 hold the engaging part in its normal position relatively to the plunger 74, and an additional spring 81 of greater strength than the springs 80 tends to force the lower end of the plunger 74 laterally to its normal position. As the plunger 74 descends, the engaging part .75 l coiiperates with the upper face 82 of the support 79 and then automatically rocks on its pivot 77 for cooperating with the face 7 8 of said support.

The operation of the preferable construction of this invention is as follows: The carriage 7 is adjusted laterally into position, the supports 1 2 are moved lengthwise to project the requisite distance, and the article to he stayed is arranged upon the supports, whereupon the operator actuates the treadle 58 and the machine commences its operation. At the commencement .of the rotation of the shaft 17. the advance ends of the adhesive strips are fed forward and engaged by the stay-supports 2a, and immediately thereafter the heads 16 17 commence their downward movement and cause the knives 51 52 to sever the advance ends of the adhesive strips, and also cause the engaging parts 4 to cooperate with the faces of the supports 1 2 to afiix portions of the stays, the

arrangement of the pivots 20 21 at the inner sides of planes forming continuations of the faces 11 of said supports preventing turning 'plungers 65, whereupon said heads move downwardly, and the engaging parts 3 1 when next encountered with the article to he stayed rock automatically as a whole on their pivots and assume their position for cooperating with the faces 11 of the supports 1 2. During the additional downward movement of the heads 16 17, the plungers are moved backwardly from engagement with the rollers 68, and the cams 67 cooperate with the rollers 73 for forcing the engaging parts 3 4L firmly toward the faces 11 to affix additional portions of the stays. After the heads 16 17 reach the limit of their downward movement the cams 5o effect the return of said heads to their elevated positions, the springs 66 move the lower ends of the main bodies 13 14; toward the heads 16 17 and the shaft 47 ceases its operation upon making a complete revolution.

To those skilled in the art it will be understood that this machine is simple in construction, and is particularly efficient in operation as it tends to cause the separable edges of the sides to he stayed, to become firmly pressed together and thus makes a particularly firm and desirable corner.

The construction and operation of this machine will now be readily understood upon reference to the foregoing description and the accompanying drawings and it will be apparent that the component parts thereof may be more or less varied without departing from the spirit of this invention.
